Abstract : In this paper we present a beginning work about industrial applications using WEB technologies. Systems to study are, for example, robot arms in factories, Heating Ventilation and Air-Conditioning (HVAC) systems for commercial center or buildings, water distribution networks or power management consumption systems of corporate. WEB technologies give us new opportunities to collect the data, to analyze correlations of signals and external events, and finally to change in "soft real-time" the parameters of the managed system. But these applications can be strongly influenced by the behaviour of the communication network and its reliability. We describe the key points that we will explore in our further work.
